Functional Imaging to Develop Outstanding Service
TECHNOLOGY AREAS: Human Systems
OBJECTIVE: This effort will capitalize
kind neural imaging feasibility work; demonstrating
functional brain activation in unrestrained dogs in response to handler cues. The objective of this effort is two
first, to optimize the selection of ideal service dogs, both in ope
rational military and therapy environments, and
second, to use real
time neural feedback to optimize canine training, shortening training duration, reducing costs,
and increasing learned responses.
DESCRIPTION: Military working dogs are used in a variety
of operations, including bomb detection, search and
rescue, and drug interdiction. Service dogs are also utilized in clinical settings, as therapy dogs to mitigate
symptoms of Post
Traumatic Stress Disorder (PTSD) and Traumatic Brain Injury (TBI) in retur
members. Certain dog breeds, ideal for this work, are rare (a limiting resource) and variability in dog training and
performance limits their effectiveness in operational environments. Better selection and screening of service dogs
e that the best dogs, with optimal motivation and trainability are selected for service. Current training
regimens are driven by classic behaviorism, involving simple reward/punishment conditioning. They are time
intensive and costly, costing more than $20
,000 per dog
human pair (in clinical animal
human work pairs).
Therefore, this program will address these two problems by 1) providing quantitative means for selecting service
dogs for training and 2) providing quantifiable evidence
based methods for optim
al canine training techniques.
Canine training paradigms require a cognitive revolution to take advantage of recent advances in brain imaging. A
ever functional Magnetic Resonance Imaging (fMRI) study in awake, unrestrained dogs (Berns et al., 2012)
confirmed that the dog brain reward system in the caudate nucleus reacts to a primed reward hand signal. These
results provide a first
ever window into the brain of man’s best friend, providing a glimpse of how dogs functionally
process human trainer sign
als and to what extent different brain networks are activated by these signals.
In both the operational and clinical settings, better canine selection and screening methods would reduce training
time and costs and result in more effective service dogs. No
w, with this state
art canine neuroimaging tool in
hand, potential high
value service dogs could be screened based on their neural activation to specific handler
training cues. The hypothesis is that dogs with greater activation in the caudate nucle
us in response to handler cues
will be faster and easier to train. These experiments would result in better use of scarce canine resources (e.g., the
rare Belgian Malinois breed) and better service dogs.
The mechanisms of canine TBI and PTSD therapy effec
tiveness are not well understood, and training and
implementation methods are ripe for improvement. One hypothesis is that effective therapy dogs are better able to
sense their owner’s mental state and emotions. Some research suggests that dogs may, in fac
t, possess robust “theory
of mind” (the ability to attribute mental states such as beliefs, desires and attitudes, to another person). For example,
dogs are known to follow human’s gaze and pointing (Kirchhofer et al., 2012) and show contagious yawning, mo
so with their owners than with strangers (Silva et al., 2012). This method of canine neuroimaging could be used to
identify ‘brain hyper
social’ dogs ideally suited to TBI or PTSD therapy work. Correlating the dog's brain activity
within the caudate nuc
leus with neurophysiological markers of handler stress and anxiety could provide a screening
tool for dogs ideally suited to therapy work.
In addition to optimizing the selection of ideal service dogs, a canine neuroimaging tool could pave the way for
olutionized service dog training paradigms. The identification of caudate activation by Berns et al. (2012)
demonstrates that canine
imaging studies could quantify the relationship between handler signal and intrinsic reward
without reliance on a behaviora
l proxy. Currently, handlers must reward approximations of a desired behavior to
teach a dog a desired task. However, associations can be made prior to behavioral manifestation. Monitoring brain
activation in real
time could allow trainers to reward proper
brain activation patterns indicative of associative
learning. These methods could be used to quickly measure how effective a given training technique is and provide
based rationale for selecting superior training methods. They would
also increase the speed
and efficacy of canine training, useful in both operational and therapy domains.
Advances in understanding the influence of dog training techniques on the canine brain 1) will enhance selection of
trainable work dogs and 2)
will enable faster, cheaper, and more effective training of military work and
therapy dogs. Overall, this project represents a radical new method of quantitatively measuring cross
communication, coordination, and therapeutics.
PHASE I: Develop a
reproducible training method for imaging canines while awake and unrestrained. Previous
work involved training only two dogs and was trial
error based (Berns et al., 2012). A more stream
method will be needed for quickly and reliably training ser
vice dogs. The small business’s expertise in dog training
will be particularly crucial for this objective.
In Phase I, animal use protocols will be developed and approved, per normal procedures. Initial work in this field
has validated that animals can
be trained for safe and humane scanning in the fMRI (Berns et al, 2012). Similar
methods employed in this study will be needed in future dog imaging studies. The large size of some training dogs
presents a technical challenge for positioning in the scanner
. Equipment modifications will be completed in Phase I
to ensure proper access to the scanner and canine comfort in the experiments. Phase I deliverables will include 1) a
technical report and brief describing the training method, and 2) a set of experimen
ts demonstrating proof of concept
for scanning reward
related brain activity in the service dogs.
PHASE II: Finalize and validate a training method for training large dogs to undergo fMRI scanning while awake
and unrestrained. Establish performance param
eters through experiments that produce reliable brain images of
responses to trainers’ hand cues, which can be used to test ideal military dog training methods. Develop,
demonstrate, and validate protocols that combine canine imaging and simultaneous human
measures in order to examine dog
human interactions. Apply these protocols to study what dogs are best suited for
use in therapeutic situations and quantify the relationship between this suitability and clinical outcomes. Required
II deliverables will include a technical report and brief describing the training methods and findings from
canine brain scans, as well as feasibility of use in future commercial and/or military applications.
PHASE III: Law enforcement agencies train an
d use work dogs for many of the same operations as the military;
therefore, transition to this customer would be seamless. Improved canine training techniques could also be used by
commercial dog training organizations, for behavior improvement or therapy
applications. Training techniques
developed in Phase I and II will substantially reduce canine training time and costs by selecting ideal dogs and
optimizing training techniques. These techniques will be transitioned to the US Air Force, which runs the DoD
Military Working Dog Program from Lackland AF Base, San Antonio, TX (341st Training Squadron).
Advances from this program could also be transitioned to the Veterans Administration, which is running a clinical
trial on the impact of therapy dogs on the li
ves of veterans diagnosed with PTSD. Understanding the mechanism and
communication between canine and human will facilitate therapy dog support for veterans with PTSD.

sensitivity Optomechanical MEMS Accelerometers
TECHNOLOGY AREAS: Sensors, Electronics
OBJECTIVE: Develop a chip
integrated optomechanical micro
electromechanical systems (MEMS) acceleromet
with 100 ng/Hz^1/2 sensitivity and 10 kHz bandwidth using high finesse optics to readout and dynamically tune
DESCRIPTION: Inertial navigation systems (INS) are a critical asset to the DoD in environments where GPS is
either denied o
r unavailable. At the heart of these systems are precision acceleration and rotation sensors. Recently,
based accelerometers have found widespread use in INS owing to their small size and ease of fabrication.
However they still lack the sensitivity an
d bandwidth required for accurate long
distance navigation. Typically,
MEMS accelerometers use capacitive measurement; their sensitivities are limited by thermal
electronic noise in the
readout circuitry . Optical interferometric methods eliminate elect
ronic noise and can approach the thermal
mechanical limit , . This thermal
mechanical noise imposes a fundamental trade
off between the sensitivity
(ath) and bandwidth (BW) of the accelerometer: ath proportional to (BW/mQ)^1/2, where m is the mechani
resonator mass and Q is its quality factor. Therefore, to achieve a high sensitivity for a given bandwidth, the product
mQ needs to be maximized. Furthermore, for high bandwidth devices, a high resolution displacement (x)
measurement is required (x pro
portional to BW^
2), thus imposing requirements on the finesse (F) and input power
(P) of the optical readout cavity (x proportional to (F^
1/2)), which is ultimately limited by laser shot noise. For
example, to achieve a sensitivity of a few ng/Hz^1/2
at a bandwidth of 10 kHz, one would require mQ > 1 kg and F
> 1000. Such a sensitivity and bandwidth combination has not been achieved in a commercial device and would
reduce the INS error, allowing longer
duration navigation in the absence of GPS.
tly, accelerometers based on optomechanical devices have been developed, which exhibit a sensitivity of a
few ng/Hz^1/2 with a bandwidth greater than 10kHz, in a compact form
factor , . Optomechanical devices are
strongly coupled optical and mechanic
al systems, in which a high finesse optical cavity is used to both measure and
quality MEMs. Such devices have enabled optical radiation
pressure cooling of MEMs to their
quantum ground state , eliminating thermal noise and enhancing the
achievable bandwidth by broadening the
mechanical resonance without loss of sensitivity. Furthermore, the cavity
enhanced optical field enables
displacement measurement at the standard quantum limit , an important fundamental limit for acceleration
sing. Finally, utilizing the high circulating power achievable in a high finesse cavity, one can dynamically control
the bandwidth of the MEMS accelerometer via the optical spring effect , thus enabling unprecedented in
control of accelerometer per
While optomechanical devices have demonstrated exciting results in the laboratory, significant development is
necessary to construct a robust packaged device that incorporates the laser, the optomechanical device, and optical
PHASE I: Design a robust, packaged MEMS accelerometer with high
sensitivity optical readout approaching the
standard quantum limit for displacement measurement. Such a system should exhibit high optical
coupling such that a pump laser can man
ipulate MEMS parameters such as resonance frequency and damping rate.
The chosen work should be compatible with an accelerometer with less than100 ng/Hz^1/2 sensitivity and greater
than a 10 kHz bandwidth. Exhibit the feasibility of the approach through a
laboratory demonstration. Phase I
deliverables will include a design review including expected device performance and a report presenting the plans
for Phase II. Experimental data demonstrating feasibility of the proposed device is favorable.
PHASE II: Fa
bricate and test a prototype device demonstrating the device performance outlined in Phase I. The
Transition Readiness Level to be reached is 5: Component and/or bread
board validation in relevant environment.
PHASE III: Once developed, compact, integrat
ed optomechanical accelerometers with high
sensitivity and high
bandwidth would greatly improve military inertial navigation systems, requiring less frequent error correction and
updates from GPS. Innovations in Phases I and II will enable such devices to
transition out of the laboratory and into
fieldable devices. MEMS accelerometers find widespread use in civilian products such as cellphones, seismic
physical and oil exploration), automobiles and gravitational wave detection.

Development of Gravitational Radiation Technology for Military Applications
TECHNOLOGY AREAS: Informati
OBJECTIVE: Demonstrate key technologies to enable application of gravitational radiation theory and research to
military communications and navigation.
DESCRIPTION: There is a need for world
wide communications and navigation systems which do
not need a sky
view link or line
sight and which are less vulnerable to threat activity. Satellite communication and navigation
systems are vulnerable to interdiction and are expensive to maintain and operate.
One, very high risk approach is the ada
ptation of gravitational radiation (GR) to communications. GR is unaffected
by obstructions such as the mass of the earth and thus offers a promise of world
communications and navigation systems.
The scientific communities of the Unite
d States and other countries have devoted substantial resources to GR theory
development, technology development, and experimentation to observe cosmological radiation. The first scientific
experiments to detect GR were performed in the U.S. with weber ba
rs. More recently, the U.S. has expended
significant resources in developing the science and technologies for the Laser Interferometer Gravitational
Observatory (LIGO). Foreign countries are also investing in research in similar activities such as M
The Netherlands), Virgo (in Italy), GEO 600 (in Germany), and TAMA 300 (in Japan). The scientific community is
optimistic that GR will be directly detected within the next decade.
The transition of the GR science and technologies to militar
y GR applications requires significant additional
innovative research in several enabling technology areas beyond those of interest to the cosmological GR
researchers. A successful GR communications system will require both a GR transmitter and a GR recei
Current technology development is focused solely on GR detectors. The system needs to allow adequate bandwidth
for communications. Current scientific GR detectors operate in the sub
Hz to few KHz range. The size of the GR
system needs to be milita
rily useful. The current LIGO systems in Washington and Louisiana have detector arms
several kilometers long. Implicit in the above is the most significant challenge, i.e., the detection of gravitational
radiation. GR has not yet been directly detected.
This topic seeks innovative concepts for the application of GR to military communications. The concept should be
supported by scientific literature or analysis based upon general relativity theory or quantum mechanics theory. The
concept should provide
sufficient detail to permit the high
level visualization of a system and the identification of
key technologies that need to be developed. A field or laboratory validation of one or more key technologies is
essential. The maturation of the concept shoul
d be phased with definitive advancements in technology.
PHASE I: Develop the underlying scientific approach to achieving a GR
based military communications system.
Define the underlying technologies required to implement the system. Perform an analysis
of the proposed system
to include an estimate of the magnitude of GR emitted and an estimate of the sensitivity of the GR receiver.
PHASE II: Conduct an experiment to demonstrate one or more of the critical technologies needed to implement a
focus should be on the generation and detection of a GR carrier wave and not on the transmission of
information. A fully successful experiment would result in the generation and detection of GR.
PHASE III: Initially, a successful GR communications sy
stem could replace existing high
based systems to reduce vulnerability. Eventually, it could replace satellite
based communications and
navigations systems. Eventually a successful GR communications system would replace
existing high capacity,
point communications systems. This would reduce requirements for extensive ground
infrastructure and maintenance.

A Flexible and Extensible Solution to Inco
rporating New RF Devices and
nto EW/ ISR Networks
TECHNOLOGY AREAS: Information Systems
OBJECTIVE: Develop a solution that will allow for seamless insertion of new Radio Frequency (RF) devices and
capabilities into EW/ISR networks. The newl
y added devices/capabilities should be readily available for providing
services to the various applications running on the network. The goal is to support addition of new devices to
multifunction networks in the field, without software changes elsewhere in
DESCRIPTION: In military applications, RF devices constitute a heterogeneous network of receivers/ transmitters
deployed primarily for the purpose of communicating tactical information. However, current RF devices are highly
versatile and th
us have the potential of fulfilling various functions in support of various tasks such as Situational
Awareness, Electronic Warfare/Intelligence, Surveillance and Reconnaissance (EW/ISR). In the highly dynamic
warfare environment, such EW/ISR networks shou
ld be easily extendable to incorporate new device types and to
support additional applications .
One of the prerequisites for achieving this goal is the development of a language that can be used to describe both
the capabilities of RF components and t
heir current operational status. While some limited capabilities of this kind
could be achieved by the use of XML coupled with an appropriate DTD , such an approach would be limited by
the XML’s lack of formal semantics. In particular, descriptions of d
evice capabilities would have to be provided in a
strictly prescribed format in order to be processed by the network infrastructure. Exchange of capability descriptions
would consume substantial bandwidth, since complete descriptions would need to be sent.
And finally, any
extension of the device types or status information would require a modification of the software that interprets XML
To avoid the above
described problems, this topic seeks development and/or specialization of a representat
processable semantics. It is highly desirable that the representation be based on a standard
language. Examples of such semantic languages are Web Ontology Language (OWL)  and Rule Interchange
Format (RIF) . Prior work in th
is area has resulted in an ontology to describe the various aspects of the RF device
structure and functionality . However, this ontology is not sufficient for describing all of the characteristics of RF
devices and their operational status needed for a
n EW/ISR network. Moreover, this work has not been demonstrated
in relevant scenarios. The development of such an ontology is a complex task since it requires not only coverage of
the relevant concepts of the domain, including complex relationships among t
he concepts, but also representing the
concepts and the structures of knowledge in a form that a wide and diverse community of RF experts can agree on.
Furthermore, this topic seeks innovative research on automated tools that can automatically incorporate
into an RF Situation Awareness or EW/ISR network. The research should result in a solution that demonstrates
seamless incorporation and use of the descriptions of RF components and their status by the network infrastructure.
PHASE I: Develop
an ontology appropriate for describing typical RF devices and device status information, relevant
for use of those devices to support EW/ISR tasks. Select a standards
based representation language and propose any
extensions to the language that are necessa
ry to effectively represent the ontology. Assess the limits of
expressiveness of the ontology and of the language (as extended) with respect to both current and future RF devices
and device status. Develop scenarios for testing the use of the ontology and
language in a command and control
system that selects an RF device to carry out a specified reception, transmission and/or processing task. Demonstrate
the developed solution in a simulated environment. Interact with organizations and programs that may be
the technology to assess requirements and improve their understanding of its benefits.
PHASE II: Evolve the ontology and extend the language as needed. Design and implement a run time prototype
system that supports use of the descriptions of RF c
omponents and their status in a command and control system that
selects an RF device to carry out specified reception, transmission and/or processing tasks. Develop a test
environment for evaluating the run time system under the scenarios developed in Phas
e I. Carry out evaluation
experiments accordingly. Interact with organizations and programs that may be users of the technology and adjust
the ontology, language, run time system design, implementation strategy, scenarios and tests to maximize
of successful adoption.
PHASE III DUAL USE APPLICATIONS: There is a critical military need for RF situational awareness and other
EW/ISR capabilities that exploit large numbers of networked sensors and transmitters. Work is ongoing on methods
to exploit R
F devices already in the field for other purposes to support such capabilities , reducing or eliminating
the cost of deploying special
purpose devices. Products based on the technology developed in this project will more
readily extend to incorporate a
larger range of devices, thus facilitating more rapid deployment and wider
availability of the new EW/ISR network capabilities such as RF situational awareness. Similarly, benefits are
expected in command and control systems for commercial RF device networ
ks. One expected application is real
time reallocation of spectrum among multiple cellular and public safety wireless networks enabling increased civil
data communications in normal conditions and increased public safety communications in emergency situati
without increasing total spectrum requirements. Achieving this benefit requires broad
time RF situational
awareness, which will be made more affordable and more precise through flexible addition of heterogeneous devices
to the sensor network
as enabled by the results of this project.

Modeling and Optimizing Turbines for Unstea
TECHNOLOGY AREAS: Air Platform, Ground/Sea Vehicles
OBJECTIVE: Develop an analytical software tool capable of modeling and optimizing turbine components for
unsteady flow conditions.
DESCRIPTION: Conventional gas turbine engines rely on Cons
tant Pressure Combustion (CPC) to generate the
enthalpy needed to provide the horsepower and thrust that our warfighters need. Unfortunately, CPC is a very
inefficient process and approximately 30
40% of the energy contained in a unit of fuel is wasted.
The ability to
create greater efficiency and power density using current gas turbine technology and design is extremely limited and
the marginal rate of return in dollars and technology invested versus efficiency and power density is decreasing.
The DoD a
nd Industry spends millions of dollars to achieve fractions of a percent increase in fuel efficiency.
Increased SFC directly translates into greater range, endurance and capability for our military.
Pressure Gain Combustion (PGC) addresses the largest so
urce of inefficiency in gas turbine engines and offers the
greatest potential for improving combustion efficiency and reducing Specific Fuel Consumption (SFC). It is
estimated that integrating this technology into current or future engines will decrease S
FC by 10
20% and increase
power density by 20%. Although PGC has demonstrated efficiency, it is not without its drawbacks. Almost every
PGC concept developed whether Pulse Detonation Engines (PDE), Rotating Detonation Engines (RDE) or Wave
es unsteady flow conditions. Conventional gas turbines are optimized for steady flow conditions and
introduction of unsteadiness in pressure, temperature, and/or swirl angle can have detrimental effects on turbine
efficiency. Without the development of a h
ighly efficient turbine capable of operating across a wide range of
temperatures, pressures, and incidence angles, all gains made by the combustors will be lost when PGCs are
integrated with turbines. Efficient turbines capable of operating in highly unste
ady regimes are needed in order to
fully achieve the energy benefits PGCs offer. The current State of the Art for this technology is TRL 2. At the end
of this STTR it is anticipated that an optimized turbine can be designed and tested to validate the sof
PHASE I: Develop an analytical software tool capable of modeling and optimizing turbine components in unsteady
flow. Select current or previous PGC data (unsteady flow to the turbine) as input to develop an analytical software
tool capable of mo
deling and optimizing turbine components for unsteady flow conditions and increasing efficiency.
The Phase I deliverables will include monthly status reports and a Final report.
PHASE II: Utilize the software tool developed in Phase I to design and manu
facture an optimized first stage high
pressure turbine and test it in an operationally relevant environment. The target Technology Readiness Level (TRL)
for this component should be 4
5. Deliverables include: a prototype of the optimized high pressure turb
status reports, and a final report that contains test data from the optimized component.
PHASE III: This technology is applicable to the Navy, Air Force, Army, and Marine Corps gas turbine engines and
their use in aircraft, ground vehicle, an
d ship propulsion. Significant fuel cost savings, reduced logistics footprint,
and an overall increase in turbine efficiencies will reduce dependency on fuel and have a profound impact on
national security. This technology has commercial gas turbine appl
ication in aircraft and commercial ship
propulsion; and gas turbine
power generation. The ability to model and optimize turbine components for unsteady
flow conditions is essential in the ability to design pressure gain combustion turbine engines in the
gain combustion technology has the potential to reduce specific fuel consumption by 20% and increase power
density by 20%.

Novel Extensible Design Approaches for Advanced Aircraft Composite
TECHNOLOGY AREAS: Air Platform, Materials/Processes
efine a low
composite structural toolset geared towards expediting
aircraft design and development, while at the same time leveraging
block approach to structural
verification for enhanced airframe assurance.
SCRIPTION: Advanced composites
enable high performance aerospace structures, including extensive tailoring
to particular applications, fastener elimination, weight reduction, improvements in fatigue resistance, and corrosion
prevention. Some essential chal
lenges for modern composite design, fabrication, and certification include the
integration of structural design detail with repeatable manufacturing processes, which must include both material
and process control. Typically, the design problem is dominated
by considerations of design details, manufacturing
flaws, and service damage, all of which cause local stress concentrations.
Robust approaches to structural assurance explore strength, fatigue, and damage tolerance issues, and tend to have a
dency on multi
scale sample tests. This design and testing approach tends to have enormous cost and
schedule impacts, effectively raising the barrier to entry of advanced composite structures into major DoD
This effort intends to develop struct
ural architectures that speed development and qualification of composite aircraft,
which has broad benefits to DoD, DARPA, and the private sector in reducing cost, increasing content re
In particular, novel solutions are
sought that would allow extensive re
use of parametric elements in structural design
of composites to achieve expedited design, verification, validation, and airworthiness certification or qualification.
By raising the level of structural design abstracti
on to higher orders, both design engineering and verification
activities could be effectively abbreviated while increasing design confidence.
While conventional design processes use a set of material allowables verified at c
level, the end goal of th
effort would be to develop a stochastically validated, open, extensible database typical aircraft component
geometries, which include allowable properties, based on key parameters for geometry, materials, and defined
manufacturing process standards.
These properties should be applicable to a defined set of configurations for key primary and secondary structural
elements, including for example, spars, ribs, skins, doors, landing gear, and associated composite to composite and
composite to metal joints
. Each of these components should include definition of parameters that permit sizing to
necessary loads, and consideration of buckling and other potential failure modes of the structures based on probable
For reference and guidance, on
e may refer to the government publication, ANC
18, which defines properties for
wooden aircraft structural materials and guidelines for structural member and joint design. Although obsolete,
18 offers relevant guidance to this effort, beca
use it provides a novel
of design rules for non
homogenous structures. Wood, considered the original filamental composite, is actually a more complex material to
design with, possessing more key parameters on type, condition, and alignment of the mater
ial with loads than are
normally considered for modern composites in airframes.
PHASE I: Design and specify a preferred material set and set of basic components, perform analytic justification of
chosen parametric geometries. Define robust approach for u
ncertainty characterization and tracking. Develop an
analysis of predicted performance, and define key technological milestones. Phase I deliverables will include a
description of the proposed material set, proposed component set, analytic justification of
applicability, and definition of processes required to quantify and track performance uncertainty from design
PHASE II: Develop, demonstrate, and validate the basic approach to component parametric definition, stoch
verification, and quantification and tracking of uncertainties. It is anticipated that this demonstration will occur in a
laboratory setting, but demonstrate multi
scale parametric element application, uncertainty quantification, stochastic
ion, design application, process verification, and representative simulation in a certification process flow.
PHASE III: This novel architectural approach
has potential for use in civil
certified aircraft structures, inclusive of
aircraft certified to 14
CFR PART 23 and 14 CFR PART 25. If successful, this methodology has the potential to
directly transition to the Air Force Research Laboratory’s Composites Affordability Initiative. Additionally, future
unmanned aircraft programs, including demonstration p
rograms executed by DARPA, may have particular benefit
from this structural architecture approach and associated methodology. An alternate military transition path would
be inclusion of this structural approach into a future aircraft program of a record.
